Shifts on the events page are related to the event. For example, the staff is needed for a conference. In this case, a conference is an event, and shifts created for the event will be used to hire staff for that particular event.
On the event view, empty shifts and open shifts have a pink colour. You can identify an unpublished shift on the event page with a dotted border.
The numbers in fractions show positions filled and total positions. For example, ½ means 1 position filled out of 2 total positions.
For a quick view of the shifts, hover over a shift and click the view icon as shown in the image below. You can edit and assign the shift from the detail view. Click the info (i) icon for the shift details.
